GBIC timing parameters for GBIC management
Parameter Symbol Min. Max. Unit Unit Conditions
TX_DISABLE assert time t_off 10 μsec
Rising edge of TX_DISABLE to fall of output signal
below 10% of nominal
TX_DISABLE negate
time
t_on 1 mec
Falling edge of TX_DISABLE to rise of output
signal above 90% of nominal
Time to initialize,
includes reset of
TX_FAULT
t_init 300 msec
From power on or hot plug fter V DD T > 4.75 volts
or From negation of TX_DISABLE during reset of
TX_FAULT.
TX_FAULT from fault to
assertion
t_fault 100 μsec

V DD T < 4.5 volts)
TX_DISABLE time to
start reset
t_rest 10 μsec TX_DISABLE HIGH before TX_DISABLE set LOW
RX_LOS assert delay t_loss_on 100 μsec
From detection of loss of signal to assertion of
RX_LOS
RX_LOS negate delay t_loss_off 100 μsec
From detection of presence of signal to negation of
RX_LOS
